Here's three more .pars from my archives, with .frm.  ..20 uses the same formula as ..19, but will send it again in case someone didn't get it with the ..19 post.  ..21 & ..22 use the same formula (sqr(1/fn)) which is part of the basic package and should be available if you have the basic program files.
 
Enjoy.
